Fuse-links type CEF are designed to protect distribution transformers, cables, overhead lines and other apparatus against thermal and dynamic effects of short-circuit currents. Key benefits: Lower power losses by average level of 20 % comparing to previous design, generating additional savings during product life-cycle

2019 ABB Backup fuses must be used in series with an expulsion fuse: –Copper fuse element with precision notches for high fault currents –The expulsion fuse protects the backup fuse from currents it cannot interrupt –The two-fuse approach minimizes the …

Technical guide, covering the most important aspects of HV fuses, based on ABB product portfolio.

The ABB Installation Products Hi-Tech® fuse application coordination tool ("the program") is designed for use by electrical utility specification engineers, transformer designers and …

fuse-element in high-voltage fuses is high purity silver. Due to the high temperatures of the fuse-links observed during operation at rated conditions, the use of a material like copper may result in an unjustified breaking of the fuse-element as a result of oxidation processes. High-voltage fuses using copper may also change their

This new fuse incorporates over 20 years of field-tested Hi-Tech full-range fuse technology combined with a new visual indicating mechanism. The Hi-Tech Valiant current-limiting fuse’s special construction contains the expulsive fragments that could otherwise be emitted during fuse operation – fragments that could fall on dry vegetation and ...
